I'm thinking of upgrading from the 901 to a 510. My main reason is because I find I have to strain my neck and face muscles to get good vapour out of the 901 a lot of the time.
So, with a 510 how does the manual switch actually work? Do you still have to draw as hard on the e-cig or do you just depress the button and let the vapour build up inside and then take a draw on it?
Thanks.
